I also was unable to get through by telephone so used the email contact option given on he website. I received a helpful response within 3 hours which let us complete the necessary forms and set up appointments on line.
My husband and I attended our Legalizaciones appointments today. Everything went smoothly and efficiently and everyone we dealt with was pleasant and helpful. We arrived around 25 minutes early but only had to wait outside for approx. 5 minutes. Despite having separate appointments, we were seen together and had completed our business and left the building 10 minutes before our first appointment.
